The imposition of quotas limiting imported steel will not help the big American steel mills. In fact, the quotas will help "mini-mills" flourish in the United States. Those small domestic mills will take more business from the big American steel mills than would have been taken by the foreign steel mills in the absence of quotas.
Which of the following, if true, would cast the most serious doubt on the claim made in the last sentence above?
Quality rather than price is a major factor in determining the type of steel to be used for a particular application.
Foreign steel mills have long produced grades of steel comparable in quality to the steel produced by the big American mills.
American quotas on imported goods have often induced other countries to impose similar quotas on American goods.
Domestic "mini-mills" consistently produce better grades of steel than do the big American mills.
Domestic "mini-mills" produce low-volume, specialized types of steel that are not produced by the big American steel mills.
P:小型的本土mills将会从大型钢铁企业那里拿走更多的生意，比起在没有进口限制令的情况，被国外钢铁企业拿走
C:钢铁进口限制令不会帮助美国的大型钢铁企业，而是帮助mini-mills。
choice b, 进口钢铁的质量和美国本土大型钢铁企业生产的钢铁质量相当。 irrelevant, 无法解释为什么mini-mills抢走大钢铁公司的生意
choice e, mini-mills生产低产量、特殊型号的钢铁，这种是大厂不会生产的。correct
